Entry, Exit, and Supply Curves: Decreasing Costs

TL;DR

Decreasing costs lead to industrial clusters through a virtuous cycle.

Transcript

♪ [music] ♪ - [Alex] Today we're going to wrap up our discussion of entry, exit and supply curves by talking briefly about the fascinating case of the decreasing cost industry. What's important and interesting about decreasing cost industries is that we think that they explain clusters. If you look around the world, you'll see places like Dal... Read More

Key Insights

• Decreasing cost industries are characterized by reduced costs as output increases, leading to the formation of industry clusters.
• Clusters like Dalton, Georgia, Silicon Valley, and Hollywood arise when local industry costs decrease due to increased output.
• Initial firms in a location create local knowledge and attract specialized workers and suppliers, fostering further industrial growth.
• The presence of multiple firms in a cluster leads to a virtuous cycle of reduced costs and increased output, attracting more firms.
• Clusters continue to grow until they gain a significant advantage, making it unfeasible to produce the same goods elsewhere.
• The decreasing cost industry is less common but important, as it explains the formation of economic clusters.
• Examples of decreasing cost industries include carpet manufacturing in Dalton and technology in Silicon Valley.
• Clusters benefit from local educational institutions that support industry-specific knowledge and skills development.

Questions & Answers

Q: What is a decreasing cost industry?

A decreasing cost industry is one where costs fall as output increases. This happens because as more firms enter the industry, local knowledge and specialized inputs become more accessible, reducing production costs. This type of industry often leads to the formation of clusters where firms benefit from shared resources and knowledge.

Q: Why do industrial clusters form in certain locations?

Industrial clusters form in certain locations due to the decreasing cost industry phenomenon. Initial firms create local knowledge and attract specialized workers and suppliers, which makes the location more attractive for other firms. As more firms enter, costs decrease further, creating a virtuous cycle that strengthens the cluster's economic advantage.

Q: What are some examples of decreasing cost industries?

Examples of decreasing cost industries include carpet manufacturing in Dalton, Georgia, technology development in Silicon Valley, and film production in Hollywood. These industries benefit from localized knowledge, specialized labor, and supplier networks, which reduce costs and encourage more firms to enter the market, forming strong industrial clusters.

Q: How do educational institutions support industrial clusters?

Educational institutions support industrial clusters by providing industry-specific training and education. In clusters like Dalton, Georgia, community colleges offer courses that teach the techniques needed in carpet production. This ensures a steady supply of skilled workers, which is crucial for the cluster's growth and competitiveness, further reducing costs for firms.

Q: What role does local knowledge play in cluster formation?

Local knowledge plays a critical role in cluster formation by providing specialized insights and skills that are essential for industry success. When an initial firm establishes itself, it creates expertise in the area, which attracts more firms seeking to benefit from this knowledge. This accumulation of expertise reduces costs and enhances the cluster's attractiveness.

Q: Why is Dalton, Georgia known as the 'Carpet Capital of the World'?

Dalton, Georgia is known as the 'Carpet Capital of the World' because it hosts a significant concentration of carpet manufacturers. The initial presence of a carpet firm led to the development of local expertise and attracted specialized suppliers and workers, reducing production costs and encouraging more firms to locate there, creating a dominant cluster.

Q: How does a virtuous cycle contribute to decreasing costs?

A virtuous cycle contributes to decreasing costs by creating a positive feedback loop where increased output leads to reduced costs, attracting more firms. As more firms enter, they bring additional resources and knowledge, further decreasing costs and encouraging even more firms to join, thereby reinforcing the cluster's economic advantage.

Q: What distinguishes decreasing cost industries from other types?

Decreasing cost industries differ from other types by exhibiting reduced costs with increased output, unlike constant or increasing cost industries. This unique cost structure allows them to form strong clusters, as firms benefit from shared resources and local expertise, leading to a competitive advantage and a concentration of industry in specific locations.

Summary & Key Takeaways

• Decreasing cost industries create economic clusters where increased output leads to reduced costs, attracting more firms. This virtuous cycle explains the concentration of industries in specific locations, such as Dalton, Georgia for carpets and Silicon Valley for technology.

• The initial firm in a location generates local knowledge and attracts specialized workers and suppliers, which draws in additional firms and reduces costs further. This process continues until the cluster gains a significant advantage.

• Clusters benefit from local educational institutions that teach industry-specific skills, further supporting the cluster's growth. Decreasing cost industries, though less common, play a crucial role in explaining the formation of these economic clusters.
